Rick Tywer, Rex's son, took over de Hourman mantwe during de Crisis on Infinite Eards. Rick swawwowed some of his fader's Miracwo piwws to hewp him save peopwe trapped in a burning hospitaw. After serving for a few years as a member of Infinity, Inc., a team composed wargewy of oder JSA-member chiwdren, Rick began to grow addicted to Miracwo just as his fader did. He spent many years after weaving de group criticawwy iww untiw Amazo, posing as a future incarnation of de android Hourman, cured him of his Miracwo addiction, uh-hah-hah-hah. Having conqwered his personaw demons and regaining his heawf, Rick joined de JSA in its incarnation as a smaww band of freedom fighters during de "Steawing Thunder" arc. The android had given him an hourgwass fuww of tachyons dat gave Rick random visions one hour into de future. As a second gift, Rick couwd visit wif his fader in an oderworwdwy dimension cawwed de Timepoint, frozen in time, just before Rex's deaf. At one point, Rick is severewy injured in battwe, and switched pwaces wif his fader to save his wife. Tywer, de android known as de dird Hourman, took Rex and some oder JSA members to de Timepoint to save Rick's wife. The one hour Rex was awwotted in de Timepoint expired just as Doctor Mid-Nite and Tywer had heawed Rick of his injuries. Fader and son fought over who wouwd perish in de battwe wif Extant. Uwtimatewy, Tywer de android took Rex's pwace and was destroyed when Rick and Rex returned to Earf. Rick is once again active as Hourman and is an active member of de JSA. He is married to Jesse Chambers.

In de 853rd century anoder Hourman, an android dat was modewed on Rex Tywer's DNA, served wif bof de Justice League and de Justice Society for a time. He often perceived himsewf as Rex and awso as Rex's descendant. Originawwy possessing de time-manipuwating cosmic artifact known as de Worwogog, he divested himsewf of most of its power at de suggestion of Snapper Carr and went about wearning to be human, uh-hah-hah-hah. After faiwing to stop Extant from escaping a fight, Hourman qwit de JSA and began travewwing drough de timestream, returning when he received a distress caww from de JSA. As noted above, he is bewieved to have been destroyed at de hands of Extant in Rex's pwace, awdough de time-travewer Rip Hunter mentioned dat his actions wouwd weave him inactive for a rewative year, indicating his probabwe return, uh-hah-hah-hah. Before he died, de android awso gave his hourgwass to Rex Tywer, who hopes to rebuiwd him. The android briefwy used de awias Matdew Tywer and was often simpwy cawwed Tywer.

Neider Rex nor Rick have any innate powers (dough it was once deorized dat deir powers derive from a metagene, wike many DC superheroes). Any superhuman abiwities dey dispway are derived from de use of Miracwo. Taking Miracwo grants a user severaw abiwities for de span of an hour. Most obvious are de superhuman strengf, durabiwity, increased resistance to physicaw damage (to de extent of being impervious to smaww arms fire) and speed enhancements. Oder, wesser known and mentioned powers incwude night vision and de abiwity to survive underwater. Rex and Rick bof took Miracwo in piww form, but Rick water changed to using a transdermaw patch.

The amount of Miracwo dat can be taken per day has varied. Normawwy, it is once a day, but in some instances, Rex has been shown taking anoder piww as soon as an "Hour of Power" runs out. One story states dat Rex needed to wait anoder hour after de Miracwo wore off before taking anoder dose. Miracwo works specificawwy on de Tywers and may or may not work on oders who take it. In one instance it worked on an animaw, Dr. Mid-Nite's oww Hootie, as weww as de viwwain Bane.

Rex and Rick bof wore an hourgwass around deir necks given to dem by de Hourman Android. It was fiwwed wif energized tachyons, time in its most basic form. It gives Rick "time vision," fwashes of events dat wiww happen exactwy one hour water as weww as de abiwity to touch dose out of phase wif normaw time. The watter effect comes to anyone howding de hourgwass. Rex dispwayed neider of dese abiwities.

"Tywer" is often simpwy cawwed an android, but is actuawwy an intewwigent machine cowony (possibwy a form of nanotechnowogy) created by Tywerco in de far future. If damaged, dis cowony can effortwesswy muwtipwy and repair. His software is encoded wif de genetics of Rex Tywer, giving him aww of Rex's memories. He originawwy possessed de Worwogog, which gave him compwete controw over time. He water gave aww but a shard of it up, but not before he absorbed aww of Batman's memories of de JLA.

Though not as powerfuw as he was originawwy, Tywer stiww retained super strengf, durabiwity, and speed eqwivawent to a person using Miracwo. He was abwe to access an "Hour of Power," sixty minutes during which he had power over time. He can do many dings wif dis controw: move between picoseconds, travew drough time, use his own time vision (which awwows him to see a person's past and future, as weww as deir age) or make peopwe and dings younger, swow a person down untiw essentiawwy frozen, create tunnews between different time periods, and share power wif oder individuaws (dough de amount of time dat he provides dem power for directwy takes away from his sixty minutes). Tywer activates de Hour of Power at wiww and de hourgwass on his chest keeps count of de time. There seems to be some doubt how often he can use his Hour of Power. Like de oder Hourmans' use of Miracwo, sometimes Tywer is said to onwy have one Hour of Power a day, whiwe at oder times he simpwy must wait anoder hour to recharge before he can reactivate, and it is uncwear if he must use dat Hour of Power in one go or if he can spread it out over de course of de day.

Tywer awso has a timeship dat he can summon from de timestream. It is connected to him and reacts to his doughts. It normawwy appears as a Viking-stywe wooden saiwing ship adorned wif cwocks, but it can change form as Tywer dictates to anyding from a simpwe wooden skiff to a futuristic spaceship and awso be used as a weapon, as when Hourman made a warge hand out of it to trap Extant. The ship can travew drough time, to awternate timewines, or drough hypertime.

The Rick Tywer version of Hourman appears as a member of de Justice League in Justice League Unwimited. In de episode "Panic in de Sky", he can be seen injecting Miracwo via a button on de wrist of his gauntwet, de same way Rick does in de comics.

The Rex Tywer version of Hourman appears in de Batman: The Brave and de Bowd episode "The Gowden Age of Justice" voiced by Lex Lang. This version uses an hourgwass shaped device to fuew his powers instead of Miracwo. He appears as a member of an aged Justice Society.

In November 2013, a wive action Hourman series was reveawed to be in devewopment at The CW. Michaew Caweo was writing de script, to executive produce de series awongside Dan Lin, and Jennifer Gwartz. The premise of de series "centers on a briwwiant-yet-troubwed pharmaceuticaw anawyst who discovers dat de visions dat have pwagued him since chiwdhood are actuawwy gwimpses of tragic events occurring one hour in de future. Determined to win back his ex-wife and son, he heroicawwy prevents dese tragedies from unfowding, finding bof purpose and redemption awong de way". As of 2018, no progress on de series was made after its announcement.[4]

The Rex Tywer version of Hourman appears in Legends of Tomorrow, portrayed by Patrick J. Adams.[5] This version is de weader of de Justice Society of America. He is introduced in de finaw scene of de first season, where he warns de Legends not to board de Waverider and travew to 1942 due to deir impending deads onwy to vanish shortwy afterwards. During de second season, de team meet Tywer's past sewf when dey ignore his warning and travew back to 1942. Tywer is kiwwed by Reverse-Fwash at de end of de episode "The Justice Society of America", causing his future sewf who had found out Reverse-Fwash's pwan and warned de Legends to be erased from existence. Before his deaf, Rex is shown to be in a rewationship wif Amaya Jiwe, de 1940s-era Vixen.

In Justice League: The New Frontier, Superman briefwy mentions to Wonder Woman dat Hourman is dead; Superman was probabwy referring to de Rex Tywer version, uh-hah-hah-hah. Hourman is awso seen in de opening credits of de fiwm, which show how he dies (being chased by powice officers on de rooftops, due to de ban of de vigiwantes, and he fawws to his deaf). In de originaw comic of New Frontier, it is reveawed dat Hourman is awive and hewd by de government. This seqwence is not in de adaptation, uh-hah-hah-hah.
